Wow
Been busy with life stuff for a few days, and come back to find everyone WAY ahead..
Great work Aromaz.
@bodkins, am I right thinking the circuit will work without 2n2222, just ground to first 2n3055?
I was going to post the following.. Guess I still will.. Great way to generate signal frequencies. I'm inclined to think along lines of Aromaz now, that letting circuit self oscillate is good way forward, but having done heaps of research and gotten all the parts, I might build my little signal generator anyway - should generate compression waves only meters long. That'd make wireless receiving coils the 1/4 of wavelength tesla stipulated would give high gains in power.
This stuff just blows your mind eh..
/// Here's the schematic I'm going to use as a signal generator, except adding a 12 way switch to select different coils, uh to mh. Also, another 12 way switch to select sets of caps, 1-10p variable, 10p-80p variable, 60-160p variable, 1n, 10n, 100n, etc. Also, going to add 1m ohm pot somewhere, either side if inductor, methinks.

And here's link to pic using Tranny in colpitts oscillator that has earth input to base..
